AMP ON SIGNAL CIRCUIT

AMP ON SIGNAL CIRCUIT

Description

INFOID:0000000003939266

When the audio system is turned on, a voltage signal is supplied from the AV control unit to the BOSE speaker
amp. When this signal is received, the BOSE speaker amp. will turn on.

Diagnosis Procedure

INFOID:0000000003939267

1.

CHECK AMP ON SIGNAL (BOSE SPEAKER AMP)

1.

Turn audio system ON.

2.

Check voltage between BOSE speaker amp. harness connector
B75 terminal 31 and ground.

Is battery voltage present?

YES

>> Inspection End.

NO

>> GO TO 2

2.

CHECK AMP ON SIGNAL (AV CONTROL UNIT)

Check voltage between AV control unit harness connector M39 ter-
minal 1 and ground.

Is battery voltage present?

YES

>> Repair harness or connector.

NO

>> Replace AV control unit. Refer to 

AV-455, "Removal and

Installation"

STEERING SWITCH

Description

INFOID:0000000003939268

When one of the steering wheel audio control switches is pushed, the resistance in the steering wheel audio
control switch circuit changes depending on which button is pushed.

Diagnosis Procedure

INFOID:0000000003939269

1.

CHECK STEERING WHEEL AUDIO CONTROL SWITCH RESISTANCE

1.

Turn ignition switch OFF.

2.

Disconnect steering wheel audio control switch connector M102.

3.

Check resistance between steering switch connector terminals.

Do the steering wheel audio control switches check OK?

YES

>> GO TO 2

NO

>> Replace steering wheel audio control switch. Refer to 

AV-468, "Removal and Installation"

.

2.

CHECK HARNESS

1.

Turn ignition switch OFF.

2.

Disconnect AV control unit connector M39 and spiral cable con-
nector M30.

3.

Check continuity between AV control unit harness connector
M39 (A) and spiral cable harness connector M30 (B).

4.

Check continuity between AV control unit connector M39 (A) and ground.

Are the continuity results as specified?

YES

>> GO TO 3

NO

>> Repair harness.

.

Did the power and ground supply check OK?

YES

>> GO TO 2

NO

>> • Check connector housings for disconnected or loose terminals. 

• Repair harness or connector. 

2.

CHECK HARNESS BETWEEN AV CONTROL UNIT AND MICROPHONE

1.

Turn ignition switch OFF.

2.

Disconnect AV control unit connector and microphone connec-
tor.

Check continuity between AV control unit harness connector
M48 (A) and microphone harness connector R8 (B).

4.

Check continuity between AV control unit harness connector
M48 (A) and ground.

Are the continuity results as specified?

YES

>> GO TO 3

NO

>> Repair harness or connector.

3.

CHECK MICROPHONE SIGNAL

Check signal between AV control unit harness connector M48 termi-
